VHEMP-SHAKING MACHINE.

SPECIFICATION forming part of Letters Patent a... 761,311, dated May 31,1904.

Application filed January 18, 1904. Serial No. 189,590. (No model.)

To alZ whom it may concern.-

Be it known that I, JAMES PzLownY, a citizen of the UnitedSt'ates,residing at Winchester, in the'county of Clark and State of Ken-- tucky,have invented a new and useful Hemp- Shaking Machine, of which thefollowing is a specification.

chines, and has for its principal object to provide amachine wherebyhemp which has been previously broken upon a. hemp-break ofany ordinarytype may be vigorously shaken in order to separate from the hemp fiberthe broken pieces of the woody material of the stalks which may beadherent thereto.

A further object of the invention is to provide an improved form ofhemp-shaking ma chine in which are included two separate shak mgmechanisms and means for alternatelyimparting power thereto, so thatwhile one of the shaking mechanisms is in operation the hemp alreadyshaken may be detached from the other shaking mechanism and unshakenhemp secured thereto instead;

A further object of the-invention is to provide a hempeshaking machinein which the movement mechanically imparted to the hemp to detachthefragments of woody material from the fiber is substantially like thatimparted to the hemp when shaken by hand.

A still further object of the invention is to provide a hemp-shakingmachine having means for varyingthe throw of the shakers in order tocause the action of the machine to be-gentle or. violent, as may bedesired.

In attaining the objects --above mentioned and others which willappearas the invention is more fully disclosed I make use of thenovel form ofhemp-shaking machinehereinafter fully described and claimed, andillustrated in a preferred form of embodiment in theaccompanyingdrawings, it being understood that changes in the minor structuraldetails thereof may be made without departing from the spirit of theinvention or sacrificing the advantages thereof.

In the drawings, Figure 1 1s aplan view of the complete machine. F1g. 2is a new m longitudinal section, taken on the line 2 2,

Fig. 1, and looking in the direction of the arrow thereon. Fig. 3isadetail view showing the mode of connecting the pitman with thewrist-plates. Fig. 4 is a detail viewof aportion of the apparatus.

Referring to the drawings, in which cor- "respondingparts aredesignated. by similar This invention relates to hemp-shaking ma-hcharacters of reference throughout the several views, 1' designates thebed ofthe machine, which maybe of any ordinary or preferredconstruction. Arranged transversely of the bed and substantially midwaybetween the ends thereof is the main driving-shaft 2 of the machine,which is mounted'to turn in bearingblocks 3, rigidly secured to the bed.The shaft 2 is providedat one end with a pulley 4 for the application ofpower to the shaft by means of a belt 5, which is driven by any suitableform. of motor. (Not shown.) At the 0pposite end of the maindriving-shaft 2 a large gear 6 is rigidly mounted, the gear. beingpreferably beveled, as shown, and adapted to mesh with smaller beveledgears 7 7, mounted at the adjacent ends of shafts 8 8, which turn inbearing-blocks 9 9, mounted upon the bed of the machine, as seen inFigs. 1 and 2. At either side of the bearing-blocks 3, in which the maindriving-shaft is journaled, is provided a shaker.

The shakers consist of frames pivotally mounted for a seesaw movement insuitable upright standards upon the bed of the machine, movement beingimparted to the shaker-frames by-mean's of pitmen connected with theshafts 8'8. p

The two shakers are exactly alike, and each is mounted for oscillatorymovement in suitably-braced standards 10 10, which extend upward fromthe bed of the machine. Each shaker is in the formof a frame comprising1 a square shaft 11, havmg gudgeons at the ends f 5 otally secured tothe middle bar 12 and having the other end supported upon a wrist-pin16, which is adjustably secured in a wrist-plate 17 at the end of one ofthe shafts 8. Each of the Wrist-plates 17 is provided with a pluralityof openings 18 at different distances from the center of the plate, sothat the wristpin may be set at different distances from the center ofthe plate, according to the length of stroke of the pitman which isdesired.

The means employed for clamping the hemp at the ends ofthe'breaker-frames is exceedingly simple. Each of the end pieces 13 ofthe breaker-frames is longitudinally grooved on its outer face, and arod 14 is held normally in engagement with the groove in each end pieceby means of hooks 20, provided at the ends of the pieces 13 and engagingprojecting studs at the ends of the rods 14. The end pieces arepreferably provided with latches 2O to prevent the disengagement of thehooks with the ends of the rods 14, and, if desired, the hooks may be soconstructed as to have a certain amount of resiliency; but ordinarilythe elasticity of the rods 14 will be sufficient.

In order to provide for the alternate operation of the two shakers, Ihave the gears 7 Slidably mounted upon the shafts 8, to which they areconnected by splines in the usual manner, and provide shifting-levers 21upon a supporting-bar 22 to impart the necessary sliding movementto thegears? to throw them into and out of engagement with the gear 6 upon themain driving-shaft 2. In order to enable the movement of one of theshiftinglevers to impart movement to the other shifting-lever at thesame time, I preferably arrange between the two levers a link 23, whichis detachably connected with each, so that it may be removed whenever itis desired to operate both of the shakers at once.

From the foregoing description it will be readily seen that in theoperation of the machine only one of the gears 7 will ordinarily beallowed to mesh with the gear 6 at one,

time, and when movement is being imparted. from the driving-shaft to oneof the shakers the other shaker will be at rest, so that the hemp whichhas already been shaken may be detached therefrom and unshaken hempsecured in its stead. As the shifting of the levers to bring one of theshakers to rest and impart movement to the other can be accomplished inan instant, but little time need be lost in the actual control of themachine, and

teneii two men Working at opposite sides of the ma-' chine will besufficient to operate it.

Having thus described the construction and operation of my invention,what I claim as new, and desire to' secure by Letters Patent,

1. In a machine of the character specified, a teetering member, andmeans for securing hemp thereon.

2. In a machineof the character specified, a frame mounted for seesawmovement, and means at the ends of said frame for securing hemp thereon.

3. In a machine of the character specified, a frame mounted for seesawmovement, and clamping devices at the ends of said frame for positivelysecuring hemp thereon.

4. In a machine of the character specified, a frame mounted for seesawmovement, hempsecuring devices at the ends of said frame, and means forimparting seesaw movement to said frame, said means being adjustable toprovide for swings of different amplitudes.

5. In apparatus of the character specified, a pair of vibratory frames,means for securing hemp upon said frames, and means for alternatelythrowing said frames into and out of operation.

6. In apparatus of the character specified, a vibratory frame,said framehaving a grooved member at one end thereof, and a rod disposedlongitudinally of said member and normally secured in the groovethereof.

7. In a machine of the character specified, a vibratory frame, arotating shaft, a wristplate mounted on said shaft, a wrist-pinadjustably mounted on the wristplate, and a pitman mounted upon saidwrist-pin and pivotally connected with said frame.

8. In a machine of the character specified, a pair of vibratory shakers,a main drivingshaft, a gear rigidly mounted upon the main driving-shaft,an auxiliary driving-shaft for each of said shakers, and a gear slidably mounted upon each of said auxiliary shafts and adapted for engagementwith said main driving-gear.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
